Opinion polls last year convincingly suggested this was the reason for National's slide in support, not personal support for Dotcom himself.
John Key now obviously hopes people's memory of the assault on their privacy has faded. That is unlikely to occur, especially now that the Prime Minister has reminded us he has been using his new powers to scrutinise, for instance, individuals' travel plans and follow this up by denying passports to those wishing to travel to Syria to fight the Assad regime.
Who knows, perhaps in time individuals will be prevented from travelling to concerts or conventions which are deemed to be a risk to public safety in the Prime Minister's eyes. This is precisely the Big Brother surveillance state that increased information collection and monitoring leads to.
Opinion polls continue to demonstrate New Zealanders care deeply about their privacy. The GCSB legislation allows the Prime Minister to authorise the collection of metadata - labelled "information infrastructure" - about New Zealanders and to share it with anyone he wishes here or overseas.
This includes the websites we visit and a list of all our contacts and phone calls meaning what we do and who we associate with are now the Government's business, not our own even when we are acting lawfully.
These issues will remain alive regardless of whether Dotcom succeeds or fails in his attempts to defeat extradition to the United States. It may be unwise for him to enter politics here in the meantime but he has every right to canvass politicians as to the serious issues his case has brought to light, especially those concerning privacy.
He ought certainly to fund a campaign reminding voters of the hypocrisy involving John Key's famous complaint over the intrusion into his "teapot" conversation with John Banks while at the same time being happy to snoop on the rest of us.
Privacy will be an election issue, you can bet on it.
